CLOSURE FOR CONTAINERS.

Application filed November s, 1923. Serial No. 672,653.

To all whom it may concern Be it known that I, ERNEST A. HUSSAR, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Closures for Containers, of which the following is a specification.

This invention may be embodied in a closure suitable for use with a container comprising a body .portion charged with semifluid material to be dispensed, and aneck through which the material is forced outward by pressure exerted upon it. The material may be tooth or shaving paste, adhesive paste, grease used'for lubrication, or any other material adapted to be extruded through a relatively small bore in the neck.

The body may be a collapsible tube, adapted.

to be compressed to cause the extrusion of the material, or it may be non-collapsible and rovided with means such as thepiston empoyed in a grease gun tocause the extrusion.

' and a portion of the body of a container, the

neck embodying certain features of the invention. Figures 2 and 3 are perspective views, respectively, of the valvemember and the cap hereinafter described. I

Figure 4 shows the neck, the valve member, and the cap assembled, the neck and valve member being shown in elevation, and the cap in section, the valve being in its open position. v

Figure 5 is a view similar to F igure 4, showing the valve in its closed position.

Figure 6 is a section on line 6-6 of Figure 4.

Figure 7 is a sectional view, showing the cap before its engagement with the neck.

Figure 8 isa section on line) 88 of Figure 7 e Figure 9 is a view similar to Figure 4:, showing a modification.

Figures 10 to 17 inclusive, show a different embodiment of the invention.

The same reference characters indicate the same parts in all the figures. Referring first, to Figures 1 to 8, inclusive, 12 designates the body, and 13 the tubular neck of a container. The neck is cylindrical and its bore 14 is surrounded by an annular concave seat 15. In the bore of the neck is a peripheral groove 16, and in one side of its outer end is a recess 17.

' 18 designates an internally cylindrical ca fitting the neck and provided with a crimped flange 19 at its lower end, occupying the groove 16, the cap being thus adapted to turn with ut endwise movement on the neck, confined against removal from the neck and held with its outer end or head portion spaced from the outer end of the neck. The

head portion of the cap is provided with a centrally located outlet orifice 20, and with a concave internal seat 21, surrounding the orifice.

22 designates a substantially spherical valve member interposed movably between the seat 21 and the outer end of the neck. The outer portion of the valve memberhas a convex upper face bearing on and closely fitting the seat 21. The lower portion of the valve member has a convex lower face, bearing on and closely fitting the seat/15 on the neck. The valve member is provided with a 'port 23, opening on said convex faces, and with two oppositely projecting trunnions 24, which are adapted to turn in trunnion bearings-25, formed in the cap at opposite sides of the outlet orifice 20, as shown by Figures 7 and 8. The trunnions areinterposed between said bearings and the outer end of the neck, and are adapted to turn in contact with the bearings and neck.

One of the trunnions 20 is providedwith an ear 26, formed to enter and move in the neck recess 17.

The arrangement is such that the cap 18 and the neck 14: may be located in the diflerent relative positions shown by Figures 4 and 5, either by turning the cap on the neck, or by turning the neck in the cap. When closed by the seat 21.

the Farts are in the relative positions shown by igure 4, the valve bore 23 is in aline- The ear 26 and recess 17 constitute an embodiment of coupling means for-imparting a partial rotation to the valvemember when the cap is turned, the valve member turning on an axis formed by the trunnions. The engagement of the trunnions with the bearings 25, causes also a turning movement of the valve member with the cap on an axis between and at ri ht angles with the trunnions, although t last-mentioned turning movement is not caused in the embodimentof the invention shown by Figure 9 and hereinafter described.

Itwill now be seen that a turning movement of the cap in either direction causes the valve member to turn, the result being the opening of the port 23 when-the cap is turned in one direction, and the closing of said ort when the cap is turned in the opposite irection. When the valve member is closed, its convex upper and lower portions closely fit the concave seats 21 and 15, so that the container is effectively sealed.

The outer side of the head portion of the. cap, and the outer portion of the valve member are so formed that they are substantially flush with each other when the valve member is closed, as shown by Figure 5, so-that the exposed surfaces may be conveniently 'wi ed and sterilized.

. igure 9 showsa modification of the coupling means for imparting a partial rotation to the valve :member. In this modification the valve member is provided with an upwardly projecting ear 26, engaging arecess 17" in a projection 28 on the head portion of the cap 18, the value member turning only on an axis formed by its trunnions.

' cate with 'a receptacle such as a grease or oil'- cup, to bev charged with material which passes inward through the neck when the.

It isobvious that the neck may communivalve member is opened, and is supplied by means such as a case oroil can applied & the orifice which, in this case, is 1111 in] or receiving orifice instead of an out- Qt... r

The valve member may be opened andclosed by a a'rtial rotation only, on an axis at right ang es with the axis .of the cap, as in the embodiment 'of the invention shown by va ve member, designated by 30, is of concavo-convexform, its upper side constituting a convex face fitting-t e concave'seat 21, which surrounds the orifice 20 in the cap The lower edge of the valve member 10-to 17. In this embodiment the.

e ect, trunnions, performing t e function of the trunnions 24, and adapted to-turn in flprovidedwith projections 31f1which are, in

bearings 32, formed by grooves in the outer end of the neck 13. The lower edge or margin of the valve member is inclined in dif-;

ferent directions, at opposite sides of the ears, so that the valve member is adapted to Fi res 15 and 16.

he valve member is provided with a port 33, opening on its convex face, and so arranged that when the valve member is in the position shown by Figure 15, the port is closed by the concave seat 21, and when the valve member is in the position shown by Figure 16, the port is in alinement'with the occupy either of the two positions shown by bore 14,-and the cap orifice 20, so'that the valve is o n..

The va ve member and the cap head are' providedwith interengaged coupling parts whereby, when the cap is partially rotated on the neck, the valvermember is partially rotated on an axis at right angles with the"- axis of the cap, and thus moved to either its closed or its 0 en position. In this instance,

"the said coup ing parts are an car 34, pro

je'cting fromthe convex face-of thevalve member, and a recess'35 formed in the inter- ,nal surface of the cap head and loosely receiving the stud, the recess being formed to impart a partial rotation to the valve member through the ear when the cap is turned.

The ear may be formed on the cap and the recess in the valve member, if desired. The

outer end of the neck may have a dome 13 fitting the concave side of the valve member.

In assembling the parts the valve member is placed on the neck with its trunnion projections 31 inethe bearings 32. The cap is then applied to the neck to cause the recess 35 to receive the ear 34. The lower end of the cap isthen .crimped, to en age the neckgroove 16. I prefer to provirIe a plurality of recesses 35, as shown by Figure 17, eitherrecess being adapted to receive the ear, so

that the ca may be held in either of several ositions w en lacing it on the valve mem- 'r and the nec thus minimizing the difli .culty" of locating a recess in position to receive the ear. Y

JThe trunnion projections 31 may be adapt: ed to bear yieldingly on the bearings 32,

and thus exert outward pressure on the valve member, to press its convex face against the concave seat 21. To this end the valve member may be cut, as indicated at 36 (Figure. 11) toform tongues 37, on the free ends of which the trunnion projections 31 are formed, said tongues being biased, so

that their free ends normally spring downward.
